SmCo Block Magnet

SmCo Block Magnets are high-temperature resistant (up to 350°C), corrosion-proof permanent magnets. They outperform neodymium magnets in extreme conditions, maintaining strong magnetic properties without coating. Widely used in aerospace, medical and industrial applications, these brittle but reliable magnets come in standard and custom sizes (SmCo26/SmCo28 grades).

Description:

SmCo Block Magnets are premium-grade permanent magnets offering unmatched thermal stability and corrosion resistance. These rare-earth magnets maintain superior magnetic performance in extreme operating conditions where other magnets would fail.
